rihis inyention relates broadly to internal combustion engines.

@ne oi' the objects thereoiz i to 'provide Angle and practical n1 for imgroving ertnin Characteristics of the olnirge 'for an engine of the above type. Y

i more specific objeet is to provide e'iioient end reliibie ineens for doing muy with ee d rnities found in starting inion engines under conditions jther objects Willbe in part obvious and in part pointed out hereinafter.

The invention accordingly eonsisis in the features of Construction: Combinations of elements and e'rrengenient of parts yfliieh will be exemplified in the construction hereinafter set forth, end the scope of the zipln, *n of n'hieh will be indicated in the in i: e iieeornnnnynef chewing. wherein s li ri T, ,1, shown one oi various pessime einoodnnen s of this inyention, Figl re l is n -side elei tion or" the same par ly broken :may order to disense the seruetme more elenrl i and rowing iis rehiton to the ejflirfler or en er l eoinbnstion engine. FM E, is zi detslied 'View of certain parts of the sinne; s tieliy in section and on a 3 is en end or plan Y@ Ihziraeters refer to simiyut the several Views oi i order render clearer certain features or this inserieren?, it may be noted that in the starting of aninternnl combustion engine in ;cold Weather diiiculty has been "found in properly exploding the charge. i

have found. that this is due. chiey to the 'fact that cold air does not readily and @iiieiently mix with the hydi'o-earbon `to forni a proper-charge, and also to the eiieet of the gold cylinder Walls ini condensing certain invented certain i constituents of the entering gas. .The above und otner defects are remedied in the constructions of the nature ofl that hereinafter' described.

Referring new to the accompanying drawing, there diagrammencally shown at l the Cylinder of :inl inernai combustion engine provided with n sourir plug or other igniting device, and such accessories as may permit the seine to run under' the internal to conduct thereto hyoro-oarbon of any desired type and the eir to be mixedtherewith. Conduit 6 leads from a metailic easing 7 closed at the lower end S and open et its upper end. Vithin this :easing is a remoyable screen cylinder loosely Fitting the same, and lim-ing formed therein :i plurality of screens l0 preferably o? concave form, and arranged alternately inyerse order in such manner esto build np n series of diaphragnis through which the air passes. i.

Connected with the screenv eylinder 9, as by a reinforcing member 11 and links 1Q, isa handle 13 by which the screen be removed from its casing.

The method of use :ind action of the above desoribed embodimentof this inventionis siibstmitinlly :is follows: `TWhen it is desired the en i *e the screen members interin the @eilig 7 are heated and thus to heut the air passing tl rough the This is preferably iieeompiished by nig th reen cylinder from the easing the hanche 1 3 .find pouring alittle gasoene or other fuel thereon, which is then ig- .reen elements to n high temperature. nes/e screen members being of iron or copper tend to retain the heet, and upon l eiligv replaced in the easing 'T MCKEEN MOTOR CAR ized, and its combustion brings the
